ExtractGeometer on curves called quadratrices (tetragōnizousai) for constructing the rectification of the circle and circular arcs (equivalent to the circle quadrature). The curve, earlier applied to this end by *Nicomedes(5) (late 3rd cent. bce), is also applicable for trisecting any angle, as may have been discovered by Dinostratus (mid-4th cent. bce).
